本文为大家分享了PHP微信支付实例,包括PHP微信支付源码,PHP微信退款源码,php微信支付接口,供大家参考,具体内容如下

1.JSapi支付demo(在微信客户端中点击)

<"../WxPayPubHelper/WxPayPubHelper.php");
 
 //使用jsapi接口
 $jsApi = new JsApi_pub();

 //=========步骤1:网页授权获取用户openid============
 //通过code获得openid
 if (!isset($_GET['code']))
 {
 //触发微信返回code码
 $url = $jsApi->createOauthUrlForCode(WxPayConf_pub::JS_API_CALL_URL);
 Header("Location: $url"); 
 }else
 {
 //获取code码,以获取openid
  $code = $_GET['code'];
 $jsApi->setCode($code);
 $openid = $jsApi->getOpenId();
 }
 
 //=========步骤2:使用统一支付接口,获取prepay_id============
 //使用统一支付接口
 $unifiedOrder = new UnifiedOrder_pub();
 
 //设置统一支付接口参数
 //设置必填参数
 //appid已填,商户无需重复填写
 //mch_id已填,商户无需重复填写
 //noncestr已填,商户无需重复填写
 //spbill_create_ip已填,商户无需重复填写
 //sign已填,商户无需重复填写

 $unifiedOrder->setParameter("body","贡献一分钱");//商品描述
 //自定义订单号,此处仅作举例
 $timeStamp = time();
 $out_trade_no = WxPayConf_pub::APPID."$timeStamp";
 $unifiedOrder->setParameter("out_trade_no","$out_trade_no");//商户订单号 
 $unifiedOrder->setParameter("total_fee","1");//总金额
 $unifiedOrder->setParameter("notify_url",WxPayConf_pub::NOTIFY_URL);//通知地址 
 $unifiedOrder->setParameter("trade_type","JSAPI");//交易类型
 //非必填参数,商户可根据实际情况选填

 //$unifiedOrder->setParameter("openid","XXXX");//用户标识
 //$unifiedOrder->setParameter("product_id","XXXX");//商品ID

 $prepay_id = $unifiedOrder->getPrepayId();
 //=========步骤3:使用jsapi调起支付============
 $jsApi->setPrepayId($prepay_id);

 $jsApiParameters = $jsApi->getParameters();
 //echo $jsApiParameters;
